So, I'm thinking of replacing the stock fuel tank (especially if I end up mangling the thing if the old fuel pump doesn't 'turn' like it's supposed to... brings back memories of mangling the heck out of the donor jeep fuel tank.)

There's these long bolts hanging from the belly of the Jeep that hold the straps and everything up, and I was wondering what size of wrench to use?  I can't seem to get one to work as they're either just a smidgen too small, or too large.  I tried both metric and SAE to no avail.

I'm considering cutting them as they're spattered with undercoating and covered with rust (being a michigan jeep... go figure)  and getting new ones... are they included in a fuel tank 'hanger' kit, or do they just have the 'straps' that go around the fuel tank?

Thanks,
Matt
